Here are the features in the Web Meeting SDK version 2.3.0 release.


  • Support to use SDK key and secret to generate tokens to join meetings.

Using SDK key and secret to generate tokens to join meetings

Now you can use an SDK App type to generate Web Meeting SDK Signatures. The signature also works to authenticate with the Native Meeting SDKs. To do so, follow the instructions in Generate Signature, except use the following:

const KJUR = require('jsrsasign') //
const crypto = require('crypto') // crypto comes with Node.js

function generateSignature(sdkKey, sdkSecret, meetingNumber, role) {
  // Prevent time sync issue between client signature generation and zoom 
  const iat = Math.round(new Date().getTime() / 1000)
  const exp = iat + 60 * 60 * 2

  const oHeader = { alg: 'HS256', typ: 'JWT' }

  const oPayload = {
    sdkKey: sdkKey,
    mn: meetingNumber,
    role: role,
    iat: iat,
    exp: exp,
    appKey: sdkKey, // required if using signature for Native SDK
    tokenExp: iat + 60 * 60 * 2 // required if using signature for Native SDK

  const sHeader = JSON.stringify(oHeader)
  const sPayload = JSON.stringify(oPayload)
  const signature = KJUR.jws.JWS.sign('HS256', sHeader, sPayload, sdkSecret)
  return signature
// pass in your Zoom SDK Key, Zoom SDK Secret, Zoom Meeting Number, and 0 to join meeting or webinar or 1 to start meeting
console.log(generateSignature(process.env.ZOOM_SDK_KEY, process.env.ZOOM_SDK_SECRET, 123456789, 0))

See Authentication for a description of the other fields. The Web SDK will ignore the fields specific to the Native SDK and the Native SDK will ignore the fields specific to the Web SDK. Complete documentation about this feature is forthcoming.
